Nutritional support in cirrhotic patients with sarcopenia.

Sarcopenia has been linked to oncologic and chronic diseases such as liver cirrhosis. In fact, sarcopenia is present in 25-70% of patients with liver cirrhosis. Furthermore, sarcopenia is an independent predictor of poor prognosis in many diseases. Currently cirrhotic patients are recommended to adopt a high protein diet (1.5 g/kg/day) with 30-40 kcal/kg/day and several meals throughout the day, being late evening snack intake with at least 50 g of carbohydrates of special importance. Despite the growing interest in the impact of sarcopenia in cirrhotic patients, there are still gaps in knowledge in the appropriate diagnostic criteria for this syndrome, the role of gut microbiota, as well as the most appropriate nutritional therapy.
